Features of light catching

So, on 27.10 I made a new fishing attempt, but this time with the lamp that Djon told me about. ... But now I know for sure that Delux EBT-01 26w UV is a really working thing in terms of attracting butterflies.

What was the power source?

NIKSTER, yes, steers, however, there were such thoughts yesterday that it would have flown to the tape, because the conditions were ideal.

Kharkovbut, Ventura battery 12 V, 12 Ah

Kharkovbut, Ventura 12 V, 12 Ah battery.

And through what to connect the lamp to the battery? The lamp is on 220, no?

Kharkovbut, yes, a 220 V lamp, I connect it via an inverter (voltage converter) of 12-220 V.

  

Thank you, Cap.

To be honest, I wanted to hear the details from the author: the model of the inverter, etc.

If possible, I will immediately ask about how long the battery charge lasted for this lamp.

Here it is rather interesting how long it glowed ) I have a self-made inverter calculations get about 3 hours with a 38W lamp, in real life I did not shine for more than 2 hours, the charge remained on the EMF slightly less than half )

No, I don't have a homemade one, but a purchased inverter. Brand - TBE, 300 W. The efficiency declared by the manufacturer is 0.9. I ordered it online at the Asmus store.

It was enough for almost 2 hours, so much I shone, then the inverter began to beep. Not enough, and I think it's because the battery is already dying. Today I measured its voltage, it was 11.91 V, which corresponds to a low battery. So, according to my calculations, it should be enough for almost 5 hours, for 4 for sure.

If after charging 11.9, then yes, the acc is bad, but if after discharge, then this is acceptable, but of course not in this case, because with a light bulb on 26, it really should shine for at least 4 hours.
If you have the means to buy such an expensive inverter, then you can already cast the battery, with the same duration, almost three times less weight.

Hierophis, actually a lithium-ion battery is much more expensive than this inverter. The inverter cost me 450 UAH, but for example a 12 V and 10 Ah battery is sold for 1960 UAH:
https://prom.ua/p106021743-litij-ionnyj-akkumulyator.html

It's kind of weird, the discharge current is 3A, which is not enough.
I'm not saying that the same price as the inverter)

I was wrong, the efficiency of the inverter is 80%, not 90. It was 90 on the store's website, but 80 in the instructions.

Figase, for such shishi and 80% ) According to the scheme that Okoyem laid out here, if you saw it down a little, the efficiency is up to 97% at a power of approx. 100W, from a 38W light bulb the transistors are cold)

So you can file a lawsuit.

And why in that scheme as much as 300-350 V voltage?

Well, it's permanent. after rectification and buffering, the output capacity after 220V is normal= 220 * root of 2x = 310v. Basically, elementary electrical engineering, you should know) Since there is a DC / DC converter and an output with an artificial midpoint, the output is allowed up to 340V.

Today I tried to light up the city from 16: 40 to 17: 40 (since Saturday I didn't charge the battery, so it was enough for as long as it lasted). Shone on a sand pit, which is overgrown with pines, poplars (including aspens). The result was zero, except for a small mosquito, although it would seem that the conditions were quite appropriate: there was practically no wind (sometimes it was small, then it subsided altogether), the temperature was around 9-10 degrees, the sky was overcast (it was dark all day).

There is no summer at all. No butterflies fly by in the light of a bicycle flashlight. Although it was written here earlier that scoops can also be used at temp. below 10 gr. fly. But now the tracks are wet on the street, but does it fly in November at 10 am?

A question for experienced hunters: maybe the canvas should have been installed in the "forest"? I spread it out on the border so that it could fly both from the sandy steppe and from the thickets of trees.

Perhaps the light source was too weak. In the summer, on cold and bright nights, almost nothing flies on weak lamps either.
We caught yesterday from 18.00 to 00 h near Vitebsk on the wasteland at the edge of the forest. Light sources: DRL-250, DRV-160, 2 Philips actinic tubes of 8 W each and a 90 W warm LED lamp on the ground. The temperature during fishing was +3...+4 C. The age was very weak, but there was. After 20 hours, the moon rose, Flying almost stopped. After 22 hours, it was covered by clouds - again something began to fly sluggishly. In total, 2 Conistra vaccinii were caught (I found another one on a tree trunk), 1 Agrochola lota, a pair of Erannis from the moth, and several Operophtera. The latter I saw more than a dozen males sitting on tree trunks in the dark. There were no females. There are also about a dozen different micro-lepidoptera and 1 caddis fly. Some mosquitoes were also flying under the lamp.

EvgenD, in general, the light source was proven-a UV lamp of 26 W, I already flew at it, and not only at me. What about the screen layout?

There are a lot of factors here, in addition to the screen, the temperature, for late autumn it is very warm, the butterflies could fly later. There's probably nothing left in the steppe, but we haven't reached the bushes yet.
Butterflies can fly at positive temperatures at any time of the year.

Today I tried to light up the city from 16: 40 to 17: 40 (since Saturday I didn't charge the battery, so it was enough for as long as it lasted). Shone on a sand pit, which is overgrown with pines, poplars (including aspens).

I think the screen should be set in a vertical position, so it will be more useful. And Alexander is right, there is no point in shining in the steppe, we need to move to the forest areas.

I am still interested in the question of reducing the throttle weight for the DRL-250 (so that you can check in your luggage for long-distance flights without fear of overloading).
My search led me to this article: http://cxem.net/house/1-329.php
I think this is a promising thing, but I would like to hear the opinion of the public, especially those participants who understand electrical engineering.

The question is extremely relevant, but... Judging by the failure of our collective long-term search, the reliability and / or price of EPR for the power we need remains unsatisfactory for manufacturers and they continue to produce chokes. In the field, the throttle, in any case, will be more reliable, given the unsanitary conditions and, most often, two-stroke non-invertor generators. This year we killed two 36W EPR units for trap lamps due to generator outages
The above scheme is quite workable, but there are hints of possible problems there. The circuit is very similar to that of key MOSFET manufacturers.
The only thing I managed to find from real EPR, conditionally (you need to try) - the Chinese stray EMH 150L:

Do you want to try it on the DRL-125?

And the DRL-125 will not burst from excess power?

And the DRL-125 will not burst from excess power?

I run 250 DRLku 400 W throttle, the lamp burns like a small sun and is very effective in the country with a large number of alternative light sources.

And the DRL-125 will not burst from excess power?

Denis, these EPRAS are all auto-excited circuits without exception. Accordingly, they have load feedback. I will not give a tooth(the circuitry is not known), but how much power will be pumped into the lamp depends on the lamp itself. There somewhere came across in the description a scheme for parallel switching on several lamps at the output of this EPR, which indicates an effective power feedback. I think that you can try. But I'm a little off right now

it was possible to check in the luggage for long-distance flights without fear of overloading

These things are o-o-very fond of being taken out of your luggage on long-haul flights

Firstly, it is very bomb-like, and secondly, the transportation of industrial equipment by private individuals is prohibited everywhere.
And you have to prove that the shit is not promoborudovanie, and light a light bulb.

The same, only even more acute, problem with generators, you will break your throat a hundred times to explain about power station for camping...

Generators yes, but these have never been withdrawn.

these were never withdrawn.

A couple of years ago, they seized persyuki from the comrade.
I was attacked by Filipinos a month and a half ago.

I 250 DRLku start 400 W throttle, the lamp is lit like a small sun

This is probably how lucky you are, depending on the specific copies. lamps and chokes. This combination worked for me for two nights, or maybe three. I don't remember now, because it was a long time ago. And then the lamp failed...

Lunar calendar for 2018 Don't thank me.

Perhaps someone will be interested in the option of a 220-volt lamp, after reworking, shining at the border of violet and ultraviolet, about 400-410 nm.

Take this lamp.



Redoing it:
- Breaking the slack.
- Remove silicone phosphor from LED elements.

Greetings to all, tell me who knows how UV spreads under water?
I read in the book by V. B. Golub, M. N. Tsurikov, A. A. Prokin "insect collections: collection, processing and storage of material" about underwater light traps, does it make sense to use UV underwater? it seems that at a distance of 0.5 meters, the UV weakens by 40%.
Has anyone ever used an underwater light trap?

does it make sense to use UV underwater?

Just wondering: why? Who are you going to attract underwater?

Water beetles, bedbugs, butterflies, etc. perfectly fly to the light on the shore and not only, larvae are collected by water nets, traps.

I would just like to try, because the species composition caught in this way may differ, but I am interested in coleoptera.

Just wanted to give it a try

I once tried, in Southeast Asia, stupidly filled all possible contacts of the UV tube with paraffin and lowered the lamp on wires into the pond - something floated, in small quantities - but then I was interested in fish
The same lamp hanging on the same snot near the water's edge above / in front of the white cloth attracted incomparably more insects.

Attracts their efficiency when working from a car inverter.

What do you call "economical"?

Type in the search engine "light output of different lighting sources" and ask about the subject - there is no economy there. You can't fool physics.

That is, those diodes that give an exhaust of a hundred hundred lumens per watt and 99% of light output, either exist mainly theoretically, or have a starship price and are sold exclusively by state order.
What makes sense won't give you any real advantages over pipes - but there will be problems, too, just different from pipes.

I tried diode spotlights, the result, in general, is the same everywhere: if it flies, it will fly to the hemorrhoid candle, if it does not fly , it does not fly to anything.

Please tell me who knows if there are 12v UV lamps? Attempts to climb on the Internet did not give any results. Thank you in advance!
